    Abstract: A communication control apparatus includes: a control unit configured to decide transmission power for multiplex communication in a wireless local area network (LAN) on the basis of information obtained through reception from another communication apparatus; a processing unit configured to generate a frame including transmission power information indicating the transmission power for the multiplex communication decided by the control unit; and a communication unit configured to transmit the frame generated by the processing unit to the other communication apparatus. The communication control apparatus, communication apparatus, communication control method, communication method, and program can suppress deterioration in reception characteristics of a multiplexed frame in a wireless LAN.

    Abstract: A communications device transmits and receives data via a wireless access interface in a mobile communications network. First resource allocation messages are received by communications devices to allocate one or more of plural communications resource elements of a host frequency range of a host carrier. Second resource allocation messages are received by reduced capability devices to allocate one or more of a first section of the communications resources within the first frequency range for preferable allocation to the reduced capability devices of a first virtual carrier, the first resource allocation messages identifying one or more of the communications resource of the host carrier allocated to the communications devices with reference to a first reference frequency and the second resource allocation messages identifying one or more communications resources of the first virtual carrier allocated to the reduced capability devices with reference to a second reference frequency within the first virtual carrier.
